concern: `lBe it known that a citizen of the United States, residing 1n Philadelphia, Pennsylvania, have invented after being set in a certain position, they' are held rigidly against the pressure of the plunger in order to insure the proper clamping of the cap to the bottle.

This object 1 attain in the following manner, reference being had to the accompanyine drawings, in which:

4igure 1 is a front elevation of a bottle capping machine illustrating my invention;

Fig. 2 is a sideview;

Fig. 3 is a sectional plan view on the line 3-3, Fig. 1;

Fig. L1 is an enlarged side view of the clamp; O

Fig. 5 is a sectional plan view of the clamp;

Fig. 6 is a perspective view showing one of the clamps oli the frame;

Figs. 7 and 8 are perspective views of one of the hook clamps; and

Fig. 9 is a view showing the rods serrated to engage teeth on the clamps.

My improved bottle capping machine is adapted to secure crown caps to bottles. The cap is placed on a bottle and the bottle is located in the machine. When the lever is pressed down, the plunger lifts the bottle against the crosshead. The shape of the recess in the crosshead is such 'as to crimp the capfirmly onto the bottle. This is fully set forth and described in the above `mentioned patent.

Referring to the drawings, 1 is a base, which has a foot 2 resting on a table or other support, and projecting under the table is a bracket 3 having a clamp screw 4 by which the base is held irmly to the table.. 0n each side et the bese are clamps L HARRY E. ASBURY,

5- through which passthe rods 6 carrying at their upper ends thecrosshead 7 having a centrally a plunger 9." Between the head of vthe plunger andthe end of the cylinder is a spring 10. The cylinder is flared at its lower edge and projecting at one side 'of the cylinder is a lug 11 which forms a gage when setting the crosshead in respect to the bottle.

Tn the base lis a plunger 12 carrying ka table 13 on which the bottle is mounted. 14 is a lever Jfor raising the plunger. The lever is pivoted at 15 and is connected by a link 16 to the plunger. A spring returns the plunger `to itsnormal position when the leveris released. This construction is similar to that described in the patent hereinbefore mentioned.

l have found that the ordinary hinged clamp is objectionable in that it does not accommodate itself to any inequalities in the rod, and, consequently, when the clamps are tightened they do not gra-sp the rod with sui'licient iirmnessl to hold the crosshead rigidly in position while pressure is being applied by the lever and the plunger to crimp the cap onto the bottle. This is essential in this type of machine, as the crosshead must be accurately set in respect to the table and bottles to be capped so as to insure the proper clamping of the cap onto the head oi a bottle. Therefore, I have designed my improved clamps, which I will now proceed to describe. These clamps, when applied, iirmly hold the rods in position against any pressure exerted by the lever inforcing the bottle against the crosshead in crimping the cap onto the bottle. c

Referring particularly to Figs. 3 to 6,'

inclusive, the base is made in two parts 1a and 1b, held together by screws 17, as clearly shown in Fig. 5. On the section 1a of the located cylinder 8 in which is base is a fixed jaw 18having two arms 19,

are beveled to form a Vfshaped recess for' the rod 6.

22 is a clamp jaw having a hook 23, which enses@ the bar .2.0 and les en .Mm

Vis perforated at 251501- the passage ofthe y bolt'26 havingl a head 27 at one end and threaded at the opposite end to receive the Wingnut 28. The two jaws are located, as

shown clearly Vin F ig. 3, so that when the wing-nut lis turned in one direction the two VJaws are drawn tightly against the l:rods

6, 6, the jaws having a V-shaped groove',

similar to the groove in the base,-\so asv to lit any irregularities inthe rod. Both the fixed and movable the center-so that the bearing surfaces will be at each end of the jaw andthe base, in-

suringvaneat lit.V The jaws are made extra heavy so 'that considerable pressurecan beV -l applied without straining them, as it will sons Without the liability of the parts Vbe understood thatfa machine of this character is especially adapted lforv householdl use and the parts must be made so'that they can be handled by inexperienced perbreaking. i v

'.,It wil be noticed that the hook section Y fits loosely on the bar 2O so that thejaw will accommodate itself to the rod 6. Y

In F ig. 9, I have shownV the rod having a series ofv serrations 6a to engageiteeth l on the fixed jaw, or `onthe movable jaws,

jaws Vare cutaway at sopas to'lock the rod positively to the base chine, of a'base;.a plunger in the base,- a Atable carried by 4the plunger; a lever Vfor raising theV plunger; two rods; a crosshead carried bythe rods; means for clamping acap'onto a bottle, said means beingmounted in the crosshead; affixed jaw at each side of the base through which the rods extend, each fixed jaw having a forked projection; a bar extending between the forks; almovable at each Side having a hook engaging the barrand also having a perilo-V rated projection; a headed boltjextending through the perforations on both movable jaws, said bolt being threaded;` and a nut mounted on the threadedportion of the bolt so that,` on turning the nut in one direction, the jaws will clamp Vthe rods, holding them firmly to Vthe base. j
